UV Call drops automatically in Adobe Connect

PROBLEM :- I have configured SIP account on my connect server and the connection to audio bridge drops automatically.

 

REASON :- This could be a issue with the silence level detection on the remote SIP provider where the call is automatically disconnected when no RTP media / SIP signals are been sent by Adobe connect to remote SIP provider.

Flash Media Gateway (FMG) core.00.log indicates the following lines -:

SOLUTION -:

1. Do not leave the audio conference bridge idle for silence level detection algorithim

2. Login onto the connect server , open the console page > Flash Media Gateway Settings > Server Configurations.

3. Set the “Registration” value as “Required”.

4. Decrease the value of Registration Expiration in steps of 60

5. Save the configuration and re-test the issue.

6. Repeat step 4 and 5 until the issue is fixed.
